The SDDC virtual infrastructure consists of two
regions. Each region includes a management pod, and a shared edge and compute
pod.

SDDC Logical Design

Management Pod

Management pods run the virtual machines that
manage the SDDC. These virtual machines host vCenter Server, NSX Manager,
NSX Controller, vRealize Operations, vRealize Log Insight, vRealize Automation,
Site Recovery Manager and other shared management components. All management,
monitoring, and infrastructure services are provisioned to a vSphere cluster
which provides high availability for these critical services. Permissions on
the management cluster limit access to only administrators. This protects the
virtual machines running the management, monitoring, and infrastructure
services.

Shared Edge and
Compute Pod

The virtual infrastructure design uses a shared
edge and compute pod. The shared pod combines the characteristics of typical
edge and compute pods into a single pod. It is possible to separate these in
the future if required.

This pod provides the following main functions:

■

Supports on-ramp and off-ramp connectivity to
physical networks

■

Connects with VLANs in the physical world

■

Hosts the SDDC tenant virtual machines

The shared edge and compute pod connects the
virtual networks (overlay networks) provided by NSX for vSphere and the
external networks. An SDDC can mix different types of compute-only pods and
provide separate compute pools for different types of SLAs.
